Iometer Results (Part 1)

Lastly, we put the drives through the rigorous grind of Iometer, with different workloads and I/O queue depths. We have chosen to show results from a queue depth of 1 to 5 as this better represents the workloads a typical consumer might face.

On Iometer, the performance of both the ADATA SP920SS and Crucial M550 were pretty comparable, with the exception of the 64k streaming writes workload where the ADATA SP920SS did predictably worse. Even so, we noticed that its 64k streaming writes performance was significantly better than that of the older Crucial M500, which also uses 128Gbit NAND. Overall, performance of both the ADATA SP920SS and Crucial M550 was pretty commendable, but the top tier drives showed their worth with their overall better performance and consistency.
